Title: Elastomer or plastomer article - reinforced with bare aramid fibres alternating with flock coated aramid fibres
Inventor: ARTZ HERMAN-JOSEF ING GRAD
IPC: B29C70/68
Filed: 1980-11-03
Abstract: Aramide fibres are often used as reinforcement for plastomer or elastomer hoses, belts, etc. because of their exceptional high tensile strength and low elongation. Attempts have been made to prevent premature failures, caused by their low abrasion resistance and transverse stability by coating them with an elastically deformable coating of flocks. The increased dia. is, however, often not acceptable because of space limitations. The difficulty can be overcome by the simple expedient of alternating bare fibres, made of aromatic aramide, with aramide fibres, coated with flocks, both in the horizontal and vertical direction.

Title: Stove or room heater for solid fuels
Inventor: PETZOLD SIEGFRIED
IPC: F24B5/02
Filed: 1981-07-29
Abstract: The invention relates to a stove or room heater for combustion of inter alia even gas-rich solid fuels, with a filling and combustion chamber above a grate and combustion-air supply below and above the grate. The aim of the invention is to design a fireplace for solid fuels in such a manner that in particular even solid fuels which generate a lot of smoke can be burned free of carbon monoxide in the smoke gases under the normal conditions of a domestic chimney and thus a soot-free and tar-free residue-free combustion with maximum possible utilisation of the fuel and optimum efficiency of the fireplace is achieved. According to the invention, the aim is achieved by arranging a waste-gas, collecting and post-combustion duct on one filling-chamber wall, preferably in the region of the rear wall directly above the grate in approximately horizontal position across the entire width of the filling-chamber wall, the entire front side of which is of open design for receiving the glowing-fire cone from the combustion zone of the filling and combustion chamber. <IMAGE>

Title: Positive-displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F01C1/02
Filed: 1981-09-29
Abstract: The invention relates to a positive-displacement machine (1) for compressible media having at least one impeller chamber (displacer chamber) (3a, 3b) which is arranged in a fixed casing (2) and designed in the manner of a slot running spirally, and having a strip or tongue-like impeller body (4a, 4b) which is assigned to each impeller chamber, is likewise of spiral shape, and is retained on a disc-shaped rotor, which is eccentrically drivable with respect to the casing, in such a way that during operation each of its points carries out a circular motion delimited by the perimeter walls of the impeller chamber, and whose curvature, compared to that of the impeller chamber, is of such a magnitude that it nearly touches the inner and outer perimeter walls of the impeller chamber on, in each case, at least one sealing line which in operation advances continuously. At the same time, crescent-shaped working chambers (10-13), formed between the perimeter walls of the impeller chamber and the impeller body are displaced, while the volume enclosed by them is reduced, from an inlet (5a, 5b) to an outlet (6a, 6b). In order to improve the efficiency of such a positive-displacement machine, which per se operates without valves, it is proposed, according to the invention, for a non-return valve (14) to be arranged near the outlet (6) of the impeller chamber (3), which non-return valve prevents any back-flow of the working fluid and is expediently designed as a diaphragm valve. <IMAGE>
